Flood watch

Potent front, frozen ground might equal floods.

Flood watch

After the most-vigorous cold snap in nine years, the forecast for tomorrow reads as though it wandered in from April.

Temperatures are expected to soar into the 60s, and a thunderstorm isn't out of the question during the afternoon.

A powerful cold front will cross the region, setting off strong winds and heavy rains.

The National Weather Service has posted a flash-flood watch for the entire region, along with a high-wind watch for the Shore.

Rainfall totals of 1 to 2.5 inches are expected, and ordinarily those amounts wouldn't set off the watch alarms.

However, as result of that cold snap -- temperatures failed to reach 30 for five conseutive days, the first such stretch since January 2004, the ground below that top layer of mud is frozen.

In addition. the trees are bare, and for now the foliage much of the foliage has lost its appetite.

Since the foliage won't be absorbing the rainwater, and the ground beneath the surface is rock-hard, that increases the potential for run-off.

The weather service says it's not anticipating major flooding along the rivers. However flash flooding of smaller streams is possible, and road-ponding is all but certain.

Behind the front, temperatures drop to near seasonal normals, with an outside chance of a touch of snow Friday and again Saturday night and early Sunday.
